electrophiles for the selective C3-alkylation of 2,3-disubstituted indoles to provide 3,3'-disubstituted indolenines. These indolenines are common synthetic intermediates that are often utilized in the synthesis of complex molecules. Effective reaction conditions utilizing Lewis acid catalysts have been determined, and the scope of the reaction with respect to indole and imidate reaction partner has been
三氯乙酰亚胺酯可作为有效的亲电子试剂,用于选择性 C3-烷基化 2,3-二取代吲哚以提供 3,3'-二取代吲哚啉。这些假吲哚是常见的合成中间体,常用于复杂分子的合成。已经确定了使用路易斯酸催化剂的有效反应条件,并研究了与吲哚和亚胺酸酯反应伙伴有关的反应范围。这种化学反应提供了一种替代碱促进和过渡金属催化的方法,后者更常用于获取类似的假吲哚。
